Getting Resources$NotFoundException in Webview of Android 8 (Oreo)

Finally it worked for me!

Before my project has compileSdkVersion to 23 and com.android.support:appcompat-v7:23.1.0. After changing compileSdkVersion to 26 and com.android.support:appcompat-v7:26.1.0 in build.gradle (app) it starts working on Android Oreo.
